Presented are the results of the analysis of changes in individual and collective radiation doses of the Beloyarsk NPP personnel, starting from the startup of the first power units with uranium-graphite reactors AMB-100 and AMB-200 during their operation and final shutdown. The article summarizes the data on the irradiation of personnel and business travelers at power units with sodium-cooled fast neutron reactors BN-600 and BN-800, including the first and repeated extension of the service life, and compares collective doses for reactor units of the integral (BN-600, BN-800) and loop (BN-350) configurations by years of operation. Using the example of a power unit with a BN-800 reactor, the analysis of dose costs at the initial stages of the life cycle (construction, physical and energy start-ups) is carried out. The paper presents the main areas of work on upgrading radiation control and monitoring systems and optimizing radiation protection at the Beloyarsk NPP, including the development of 3D models of radiation-hazardous rooms and methods for route optimization of work in non-uniform radiation fields. The paper presents the main areas of work (activities) on optimizing radiation protection at the Beloyarsk NPP, planned in accordance with the ’Radiation Protection Program at NPPs’ for the period 2025-2029.
